Frequently Asked Questions

What is leak detection, and why is it important?

Leak detection is the process of identifying and locating water leaks in plumbing systems, appliances, underground pipes, or structural elements of a property. Detecting leaks early is essential because hidden leaks can cause serious structural damage, promote mould growth, waste large amounts of water, and lead to inflated utility bills. Professional leak detection methods aim to locate leaks with minimal disruption to the property by using non-invasive technologies. By addressing leaks early, property owners can prevent costly repairs, preserve water resources, and maintain the safety and functionality of their plumbing system.

What are the signs of a hidden water leak?

Hidden water leaks can be difficult to spot, but there are several tell-tale signs that indicate a problem. Unexplained increases in your water bill, damp or musty smells, discoloured patches on walls or ceilings, bubbling paint or wallpaper, and warped flooring are all possible indicators. Outside, a constantly wet patch of ground or unusual plant growth near buried pipes may also suggest a leak. If you hear the sound of running water when all taps and appliances are turned off, it’s worth investigating further. Identifying these symptoms early can save time and prevent major damage.

How is leak detection carried out?

Modern leak detection involves a range of techniques depending on the location and nature of the leak. Acoustic listening devices detect the sound of water escaping from pressurised pipes, while thermal imaging cameras identify temperature differences behind walls and floors. Moisture meters measure dampness in building materials, and tracer gas (an inert, non-toxic gas) may be pumped into pipes to detect leaks in hard-to-reach places. In outdoor or underground cases, ground microphones and correlators help pinpoint leaks beneath soil or concrete. These methods are non-invasive and allow for accurate diagnosis without unnecessary damage.

Is professional leak detection worth the cost?

While professional leak detection may seem like an upfront expense, it often saves property owners money in the long run. The cost of undetected leaks—including structural repairs, high water bills, and potential mould remediation—can be far greater than the cost of professional assessment. Additionally, leak detection professionals have the equipment and experience to find issues quickly and without guesswork, reducing the risk of unnecessary excavation or demolition. In cases involving insurance claims, a formal leak report from a qualified technician can also support the claim and streamline the repair process.

How long does leak detection usually take?

The time required to carry out leak detection depends on the size of the property and the complexity of the plumbing system. For a standard residential home, leak detection might take anywhere from one to three hours. More complex or larger-scale systems, such as commercial buildings, apartment complexes, or properties with extensive underground piping, may require additional time. If multiple leaks are suspected or if the source is particularly challenging to locate, the process could take longer. Regardless, modern detection equipment significantly speeds up the process compared to manual methods.
